Queenkan — quiet logic puzzle

Queenkan is a quiet logic puzzle in the queens style: place exactly one queen in every row, every column and every color region — and no two queens may touch, not even diagonally.

◆ Pure logic, no guessing
Every board has exactly one solution. Whenever you're stuck, there is always a next logical step waiting to be found.

◆ Hints that teach
Hints don't just reveal the answer. They walk you through the human reasoning, step by step, right on the board — "this color is confined to this row, so…".

◆ A fresh daily challenge
A new daily puzzle every midnight, the same board for everyone. Keep your streak alive.

◆ 900+ puzzles
A smooth difficulty curve from cozy 5×5 boards to demanding 12×12 ones. Expert levels call for real chains of deduction.

◆ Twist packs
· Double queens — two queens in every row, column and color.
· Twin colors — every color is split into two separated pieces, so the clues scatter and the logic deepens.

No account, no timer pressure, works offline. Just quiet logic.
